Quite a response on the PSU / Miner issue! Had to go back through a 1.5 pages in just a couple hours to catch up 
Pretty good advice from folks so far as well.
That's the issue right there then. Presuming the paperclip is in the right place and securely in the MB connector (no looseness), it may be that the PSU is hitting the 'protection' threshold and powering off.
I think was already pointed out, but you could try hooking this one up to a desktop computer (assuming you have one) and see if it makes any difference.

On just the PS with the mb cable jumped - I get 1-4 revs of the PS fan, then nothing. It's like something clicks off in the PS as soon as it ramps up.
